COMPRESSION-REGULATOR FOR EXPLOSION-MOTORS.

Specification of Letters Patent.

Patented Mar. 15, 1921.

Application filed May 20, 1919. Serial No. 298,573.

certain new and useful Improvements in or Relating to Compression-Regulators for Explosion-Motors, of which the following is a specification.

The invention has for its object a method which permits of maintaining within fixed limits the compression of explosion motors under variations of altitude.

The method consists in utilizing to th1s end an ordinary air compressor, that is to say one in which the pressure of the air at the endof the compression depends on the pressure of the air on admission and conse uently on the altitude. p

t is the variation of pressure accordin to the altitude of this compressed air'whic is employed to maintain within fixed limits the compression of an explosion motor.

In the accompanying drawing which represents diagrammatically, by way of example. one of the constructional forms of the system.

A is an air compressor drawing atmospheric air through a valve B and forcing it through a valve 0 into an air reservoir D.

The reservoir D communicates with the atmosphere by a calibrated orifice E and b a cylindrical passage closed by a piston which is fluid tight and works in this passa e. I The piston F operates a rock lever H which is adapted to oscillate about a fixed shaft 1. I

L is a fluid tight space into which open all the air supplies of the carburetor M which supplies the explosion motor: this space communicates by the pipe N with the upper part of the constant level or float which supplies the carbureter, the tank of this constant level being supplied with fuel by the pipe P which is fluid tight and does not communicate with the atmosphere.

The inlet reservoir L is provided with a valve K which is adapted to open under the action of the reduction of ressure produced by the drawing in of the air necessary to the working of the motor. The valve K is connected to the rock lever H in such a wa that pressure exerted on the piston F by t e air contained in the reservoir D acts in opposition to its opening.

R is a spring suitably initially tensioned and acting on the valve K, its action tendin to open it.

hen, the motor being in motion, the compressor A acts the air is compressed in D at a pressure which depends on the pressure of admission of the air to the compressor that is to say on the altitude.

The compressor A draws in air through the valve B, at the pressure of the surrounding atmosphere which is dependent upon altitude and compresses it, through the valve C into the reservoir D, to about double that of the surrounding atmosphere. As the motor ascends the surrounding atmosphere pressure diminishes as the altitude attained increases and consequently the delivery pressure (whichis constantly about double the surrounding or external pressure) diminishes proportionally. The calibrated aperture E is for the purpose of preventing the pressure in the reservoir D from becoming too high. Air escapes from the reservoir D through the aperture E in quantities dependent upon the difference in pressure between internal pressure in the reservoir and the surrounding air. The escape of air through E being greater as the pressure of the external atmosphere decreases and the aperture E may be so calibrated that the pressure in D may not become higher than the pressure of air supplied by the compressor.

Under these conditions the pressure in D and consequently the force which is opposed to the opening of the valve K varies inversely with the altitude.

It is the variation of this force which is opposed to the lifting of the valve K under the influence of the suction of the motor, which permits, while suitably controlling the apparatus, apressure to be obtained in stroke: the-air contained in D thus returns, when the altitude increases, to the compressor, and passes back into the atmosphere through the inlet valve B which, for this purpose, must be operated mechanically.

This system of regulating the compression may of course be equally a plied to an apparatus for the supply to t e motor of air and fuel in more than normal quantities.

What I claim and desire to secure by Letters Patent of the United States is 1. A compression regulator for an explosion motor, comprising a compressor, an air reservoir, said compressor being adapted to deliver air into said reservoir, and the reservoir having means for escape of air, acting to keep said reservoir at a pressure varying according to the atmospheric pressure, a carbureter and an inlet reservoir for the air supplied to said carbureter, having an inlet valve and means under control of the pressure in said air reservoir for operating said valve, whereby to vary the area of admission of air to the said inlet reservoir inversely to the density of the air and thereby to maintain the compression of the motor within fixed limits, irrespective of the atmospheric pressure.

2. Ina compression regulator for an explosion motor, acompressor and an air reservoir, said compressor being adapted to deliver air into said reservoir, and said reservoir having a calibrated orifice, acting to vary the pressure in said reservolr according to the atmospheric pressure.

3. A compression regulator for an explosion motor, comprising a compressor, an air reservoir, a carburetor and an inlet reservoir for the air supplied to said carbureter,

said inlet reservoir having an inlet valve to put the inlet reservoir in communication with the outer atmosphere, the valve being controlled by the pressure in said air reservoir, an air conduit connectingsaid inlet reservoir with the motor, and a communication between said inlet reservoir and the carbureter, and maintaining a fixed pressure of air in the carburetor regardless of the altitude.

4. A compression regulator for an explosion motor, comprising a compressor, an air reservoir, a carbureter and an inlet reservoir having an inlet valve to putthe inlet reservoir in communication with the outer atmosphere, the valve being controlled by the pressure in said air reservoir, and means under control of the pressure in said air reservoir for operating said valve, said operating means comprising a lever and a spring.

5. A compression regulator for an explosion motor comprising a compressor, an air reservoir fed from said compressor, and having an outlet to the atmosphere, a carbureter having a float chamber and valve, a fuel feed tank, the flow therefrom to said carbureter controlled by said valve, an inlet reservoir for the air supplied to said carbureter, said inlet reservoir having an inlet valve controlled by the pressure in said air reservoir, and having a pipe opening to the float chamber and an air intake pipe leading from said inlet reservoir to the carbureter.

In witness whereof,- I have hereunto signed my name in the presence of the subscribing witness.
